That seems way more likely than calcium build up.
Assuming you are correct...
Starting with a working filter and keeping it in a sealed bag or capping the ends would prevent complete drying. On the other hand after use it probably takes quite a long time to fully dry so unless you will be in a very dry environment for quite a long time between uses I'd guess it is unlikely to be a problem.
Storage is always going to be an issue, however. You probably don't want to store it wet to avoid mold. The other problem for me and others who live out West, is that it doesn't take long for
anything to dry. There's a lot of space out here in the dry West
And, like I've said numerous times above, unless you know about the problem, you are in for an unpleasant surprise.
